Things You'll Need

  • Waterless incinerating toilet

  • Composting toilet

  • 12-inch wide stainless steel connecting chute

  • Air compressor

  • Sealed compost chamber

  • Vent stack


These toilets are simple to install and maintain, but they do come with specific instructions on how to install the various components and materials. Follow these instructions carefully depending on which toilet you choose. All pieces will fit together easily, but they must be installed correctly.


If you notice any odors or issues with the system you have installed, there may be a problem with your system. These toilets were specifically designed to be odorless. Contact the company from which you purchased it and receive a professional consultation to avoid further issues.

Adding a restroom without a sewer or septic connection saves water.

An environmentally conscious alternative to the traditional toilet is one that does not require plumbing, sewer or septic connections. There are instances where these connections are extremely difficult anyway, such as in a cottage or tent in a rural area, or in certain climates where the ground is too cold or hostile to install pipes. Restrooms can now be added without sewer or septic in a clean, manageable fashion with low maintenance and no odor.

Waterless Incinerating Toilet

Step 1

Plan a location for the toilet that takes into account the chimney system needed for the toilet to function properly. A waterless incinerating toilet burns waste within the unit. A system within the toilet moves the waste to a special chamber for incineration after the toilet has been used.

Step 2

Place the waterless incinerating toilet on the floor of the restroom. The units are self contained and require no plumbing, sewer or septic pipes.

Step 3

Connect the chimney system included with the toilet kit. Hook up the fuel source. Connect to a power source as specified by the manufacturer. The sterile ash produced during incineration must only be removed periodically. There will be no odor associated with the waste or the incineration process.

Waterless Composting Toilet

Step 1

Place the toilet in a location that will allow you to place a pipe from the base of the toilet through the floor to the basement, outside or another place where the composting unit can be installed.

Step 2

Connect the 12-inch wide stainless steel connecting chute to the bottom of the toilet.

Step 3

Install the compost chamber in a basement or another room directly below the location of the toilet. If you do not have a basement, you can route the pipe outside. Connect the chute to the chamber.

Step 4

Hook up the air-compression system next to the compost chamber. This system will be included in the toilet kit and will provide the suction for the forced-ventilation system. Install the vent stack that will go outside from the compost chamber. Oxygen will be pulled down the toilet's chute into the chamber and out through the vent stack. The waste will be composted and made into a useful mixture for fertilizer. The removal must only occur every 10 to 15 years depending on usage.
